Dear All,

I set a page for participants to give their privacy consensus.

The question is an array column.

The first option is yes.

The second is no.

How do I prevent the survey to proceed in case of NO answer and have a message appearing, saying that to proceed the consensus is needed?
(so that they have to click yes instead of no?)

Thank you very much in advance for your help.

Best regards.

Hi, dgiacometti,
maybe better to use a multiple question with just one subquestion, like "I agree"

Mandatory question and In advanced settings: min answer count : 1

So the respondnet has to check this box before being able to proceed.

You should hide the hints and write your own explanation

Best regards

Or use quota to NO question at 0 for max answers.

But I really like the Joffm solution, think it's more elegant

Thanks you all for the solutions suggested.

Unfortunately I have to follow a strict regulation that does not allow any other solution than the one I proposed.

Participants must have the possibility of the two alternatives but they can follow only if they give consent.

And if they do not a message must appear so that they can decide to change decision or abandon the survey.

Any hints?

Thank you again.

In this case you might have to create two questions: The first one where they choose yes or no.

When yes they just proceed with the questionnaire, when no two other questions are opened. One text display question that shows the information you want and one question that looks exactly like the first question where they again can choose yes or no. With yes they proceed to the next question and continue, with no they will be "screen out" by the zero quota that Denis mentioned.

Maybe you can achieve this playing with group relevance

The 1st group only contains your screening question.

[yes] => user follows survey and go next group

[no] => dedicated group at the end of the survey with only one "text display" question( boilerplate) inviting to leave or go back for answer edition. Submit button could be disabled or not (via javascript and/or css)

I would set a quota on No, so that when someone choose No, the survey will be closed and the respondent will be screened out.

Hi, dgiacometti,

Participants must have the possibility of the two alternatives but they can follow only if they give consent.

And if they do not a message must appear so that they can decide to change decision or abandon the survey.

So, if they answer "No" to the first question, there will appear an explanation text to tell them "No, no, no, you have to click 'Yes' to proceed"?

If you do not want to follow holch's suggestion (implementing the same "Yes/No" a second time, and screen them out, if they answer "No" a second time) you have to allow your respondents to "Go back" to the first question, where they can change their mind.

In case the click "Next" they are screened out definitely.

Possible, but I do not like to allow respondents to go back.

Kind regards
Joffm

In case the click "Next" they are screened out definitely.

How would you define that after the first "no" they can go back and after the second "no" they are screened out when using the same question?

holch, I think there is a misunderstanding.

I tried to say: You can follow holch's suggestion with a second "equal looking" question.
The "second NO" is the "No" in the second "Yes/No" question.

Kind regards
Joffm

Ahh, OK, understood. I thought you had a clever way to use just one question.
